Starrett 52465 Parallel Feeler Gage Set 0.04-5mm 13pc

Product Description

The STARRETT 52465 is a 13-piece parallel feeler gage set designed for precise gap and clearance measurement in mechanical and industrial applications. Each leaf is manufactured from tempered steel for durability and consistent flex across repeated use. The set spans a measurement range of 0.04 mm to 5 mm, covering the most common clearance tolerances encountered in engine, machinery, and component assembly work. Leaves measure 4.5 inches long by 0.5 inches wide, providing a practical size for access in confined spaces. This set is a standard tool for machinists, mechanics, HVAC technicians, and industrial maintenance professionals who require reliable feeler gage performance.

This feeler gage set suits a wide range of trade and industrial applications including valve clearance checks, spark plug gap verification, bearing clearance measurement, and general-purpose fit and tolerance inspection. The parallel leaf style delivers uniform thickness along the full length of each blade, which is essential when a consistent reading across the contact surface is required. Suitable for use in residential and commercial HVAC service, automotive, and precision mechanical maintenance environments.

Installation Notes

Feeler gages are used by machinists, mechanics, and service technicians and require no installation. Before use, ensure all moving parts or components being measured are de-energized or at rest and that the equipment is safe to service. Select the appropriate leaf or combination of leaves to achieve the target clearance value, and avoid bending or forcing leaves beyond their natural flex range, as this can affect measurement accuracy. Clean leaves before and after use to prevent corrosion and ensure accurate readings.
